In the distant future, an empty spaceship is driving through the endless dark space.

This spaceship has no destination. We don't know how long it has been sailing, but it contains memories of a species that has long perished.

This species calls itself human and once inhabited a planet called Earth, it seems.

They must have had a high degree of civilization. At a certain point, they even created artificial intelligence that surpassed their own, and together, they developed such technology that allows them to create this ship.

However, no matter what, they are now nothing more than some dusts in history, disappeared at the other end of time. Long before we were born, they had died out, not a single individual remained.

Why did they make this spaceship? Perhaps, they once wanted to leave the galaxy where they were born and expand to the galaxy farther away.

Or, they just want to leave a little proof that they once existed, so that future civilizations can have a chance to know how they had loved and lived and died.

Too much time has passed, and we can never know their intentions, but only some unverifiable conjectures.

But looking at these burning memories, there is an indescribable sadness, right?
